WhatsApp switches to two-factor Authentication for 1.2 billion users
After announcing the latest application feature last fall, WhatsApp is ready to drop the beta tag and release two-factor authentication to each of its 1.2 billion users on an iOS, Android, and Windows devices.
What is Two Factor Authentication?
Two Factor Authentication is an extra layer of security that requires not only a password and username but also something that only, and only, that user has on them, i.e. a piece of information only they should know or have immediately to hand – such as a physical token.
Two-factor authentication adds in additional security to an online account by demanding a secondary method of authentication to access it. Usually a user’s password provides the first factor of authentication, and an alpha-numeric code sent as a text message usually serves as the second factor.
Two-Factor Authentication in WhatsApp
While using WhatsApp mobile application, the first factor of authentication is automatically verified when the application is being used as the same handset which has the app linked sim card installed in it.
Now you can add in another security layer for your Whatsapp account with a six-digit code.
How to enable 2FA in WhatsApp?
Follow the guide to enable multi factor authentication in WhatsApp in order to make it more secure.
Open WhatsApp > Settings > Account > Two-step verification > Enable.
Periodically after seven days, the users will be prompted to enter the passcode to log in to the application.
The update is gradually rolling out worldwide and the option to enable 2-factor authentication will appear then once the users have the updated version of WhatsApp installed.
